' A, Specification of letter:

To all whom it may concern: t I j g Be itknown that I,- Hanom K. Fansons, a citizen of'the United States residing at Southbridge, in the county of orcester and State of Massachusetts, have invented cer- ,tain new and useful Improvements in Eye- Protectors,,of which the following is a specification.

This invention relates to improvements in eye protectors and has particular reference to an improved protector especially adapted for use in the industries in those places where the user is heat. 1

One of the leading objects of the present invention is the provision of a construction of this character in which the employment of metal is reduced to a minimunnand in which all metallic parts, are disposed entirely on the outside of the protector.

is the provision of a construction ofthis nature which shall be extremely simple in construction, shall employ a minimum num ber of parts, and shall permit of the ready desired. 4

Other objects and advantages of my 1mproved construction should be neadily apparent by reference to the following specification taken in connectionwith the accompanying drawings, and it will beunderstood that I may make any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of my invention.

Figure I represents a front view of my complete protector.

Fig. II is a detailed transverse sectional view taken through one of the eye cups.

Fig. III represents a front view of a slightly modified construction.

Fig. IV represents a rear view of the lensframe for cooperation therewith.

Fig. V represents a plan view of the construction illustrated in Fig. III.

Fig. VI represents a sectional view of a modified construction. I

Fig. VII represents a detail view of a further modification.

Fig. VIII re resents a front view of a construction em odying the parts illustrated in Fig. VII.

subjected to considerable 4 protecting lenses Fig. IX..'1'epr'esents a sectional viewillus i tratingthe of said arts.

' Patented June-11, 191s.

In the drawings, in W 'ch similar 'charac ters of reference are 'emplo ed to denote corresponding parts. throug out .the several views, the numeral 1 designates the face engaging portion of my improved' edfiber or light non-metallic and relatively non-conducting material, having pressed up therefrom the e e cups 2 terminating in-the form i ustra in Fig. Lin the outwardly directe flanges 3, against which rest the 4, locked in engagement with the flanges 3, encircling the lens and flange, and retained in position therearound as b the end iece .6, which may be of any we known orm,

either screw, quick detachable clip or the .like as desired. a

A further object of the present invention My protectors may, if desired, in addition he provided with the molded inner edges roviding the nose bearing pads or guards I rotector, which 18 preferably inthe form'oi a mold asby the channel rims 5 and are preferably connected by a suitable pliable bridge member 8, although it.

will be understood that different forms of 1 bridge members may be employed if desired,

or that the entire goggle may be formed, in one piece in place of two separate parts, in either event ead bands 9 being preferably employed to retain the same in position on the face of the wearer.

In Figs. III to VI inclusive, I have illustrated a slightly difl'erent form of my invention, in which the flange 3 in place of being continuous, as is intended in connection with' Figs. 1 and II, has formed therein the recesses 10, through which may pass the clips 11 on the frame "12, the flange being preferably in addition provided adjacent the recesses 10 with .the inclined rear face 13, terminating in the reversely sloping face 14 and stop or abutment 15. The urpose of this should be at once underst and it will be seen that in assembling this form of my protector the lens is placed within the frame '12, as by placing'inside certain of the clips and snapping by the remainder thereof,

desired by reverse twisting or unlocking of the parts.

It is'to be noted that I have illustrated as employed in connection with this construction the interposed resilient ring 17 placed between the lens 4 and the flange 3, thus insuring an air and dust tight union between these parts, and at the same time being capa-. ble of yielding as the clips are placed into position, and having a slight yielding'or cushioning effect in case of a blow or the like on the lens, tending to retard or prevent breakage thereof.

In Figs. VII, VIII and IX, I have illustrated another slight modification of my construction,.in which I make use of the ring 18 adapted to encircle the eye cup 2 immediately rearwardly of the flange 3, as shown in Fig. IX, this ring bearing thereon a plurality of clips 19, certain of which may be fixed, if desired, and at least one of which is movable, as indicated in the dotted lines Fig. VIII. These clips preferably have a general channel formation for embracing the flange and lens, and in addition may be pro vided with the rearward extension 20 to prevent any pivotal movement of the clip about the ring 18. In the use of this form of my construction the movable clip is slid around on the ring 18 to suitable position, such as indicated in dotted lines Fig. VIII, and the member 17 and lens 4.- are slid in from the side into correct position on the face of the flange and beneath the fixed or immovable clips 19. After the clips have been placed in position the movable clip is given a suflicient movement circumferentially of the ring 18 to securely and satisfactorily engage and lock the lens against any loosening movement.

From the foregoing description taken in connection with the accompanying drawings, the construction and advantages of my improved protector should be at once apparent, and it will be seen that I have provided I an extremely simple and desirable construcparts without expensive threading operations or the like and am at the same time able to removably retain in position the lenses of the protector and facilitate their replacement as desired.

I claim 1 1. In an eye protector, the combination with an eye cup terminating in a peripheral flange, said flange having a plurality of notches formed therein with rearwardly and forwardly inclining portions adjacent the notches on one side, of lenses, and lens retaining rims having fingers adapted to pass through the notches and be interlocked with the rims by relative rotation of the parts, causing the fingers to ride upward on the inwardly inclining surfaces and finally engage the outwardly inclining surfaces.

2. In an eye protector, the combination with an eye cup terminating in a peripheral flange, said flange having a plurality of notches therein and inclined walls adjacent the notches, of lenses and lens rims having fingers adapted to pass through the notches and be interlocked with the inclined portions by relative rotation of the parts to detachably connect the lens rims with the flange. A 3. In a device of the character described, the combination with a mask having a bridging eye cup terminating in a channel flange, of a lens adapted to fit against the flan e and a retaining rim for the lens having ngers thereon adapted to be inserted through the channels in the flange and brought into interlocking engagement with the flange by relative rotation of the rim and flange to securely retain the same in position.

In testimony whereof I afiix my signature in the presence of two witnesses.
